Step-by-step explanation:
So, assuming that x would be the number of miles towed, this word problem gives us two linear equations:
One for Brook's Body Shop, which is y = 3x + 25
And one for Morgan Motors, which is y = 5x
We see that these two lines intersect at the point (12.5, 62.5). Remember that the x-value stands for the number of miles. So, at 12.5 miles, both companies charge the same rate.
This means that Morgan Motors is cheaper for any number of miles less than 12.5. In contrast, Brook's Body Shop is cheaper for any number of miles more than 12.5.
In conclusion, if you had to be towed less than 12.5 miles, you should go to Morgan Motors because they are cheaper for short distances. If you had to be towed more than 12.5 miles, you should go to Brook's Body Shop because they are cheaper for longer distances.
Answer:
Yes
Step-by-step explanation:
Yes it is possible to solve a quadratic equation that is not factorable over the set of integers.
The solution may vary like Integers, rationals, irrationals or complex solutions.
To find two roots of the equation we can always use the formula given below to solve a quadratic equation,
For the quadratic equation,
, we have,
If the discriminant is greater than , we get complex roots.
